Well, OK, I think most of us know what this is... looks like a cuttlefish! (edit: it is, in fact, Sepioteuthis sepiodiea, the Caribbean Reef Squid; see Colin's reply to this thread.) TONMO.com visitor Nick B. let me share this photo with you to get your thoughts... What a remarkable pose! :shock: According to Nick:
I am the manager of our local dive clubs photo contest - and one of my friends took the photo below - at night, the creature was about 4 inches, taken in Florida Keys

Thanks Nick for sharing!

What an excellent picture Nick! I never new feeding tentacles could do that.

Sepioteuthis sepiodiea The Caribbean Reef Squid

Apparantly the scientific name means 'cuttlefish like squid' so cuttlefish is close but no banana... no cuttlefish in the USA :wink:

Duly noted, thanks Colin!
